Installation

Installing via PXE works well. It requires another computer to use as PXE host, and some configuration.

Kernel

Nothing to need to be done. If you have append acpi_osi=Linux to your kernel parameters before, please remove it. Or the touchpad may not work in KDE (although it works in KDM and Gnome) and the touchpad activation key [Fn]-[F3] has no effect at all.

Xorg

Video Driver

Device Autodetection

Everything works out of the box.

Graphic Performance

The default graphic performance is the best you can currently get. It is not needed to add "optimizations" like "AccelMethod" "exa" to your xorg.conf, because these will get ignored by the current version of the Intel drivers anyway. The only thing you can add is XvMC Hardware decoding support, which allows your Intel graphics adapter to decode MPEG2 video material. To do this and set XvMC, here is a minimal xorg.conf:

Powersaving and ACPI

laptop-mode-tools

Laptop-mode-tools provides an easy way to setup most of the available power saving options, which include spinning down the hard drive and adjusting the power saving modes of the harddrive and CPU, as well as autosuspending the USB-ports, setting screen brightness, configuring the eee's own 'Super Hybrid Engine', etc.

Setup

# pacman -S laptop-mode-tools

The main configuration file is /etc/laptop-mode/laptop-mode.conf, plus there are several separate configuration files in /etc/laptop-mode/conf.d/ for the various power saving modules managed by laptop-mode-tools. The files are well commented, so it should be easy to set everything up as needed. (For more information, see Laptop Mode Tools)

To make the daemon start at boot, add laptop-mode to the DAEMONS array in /etc/rc.conf.

LCD brightness

The relevant configuration file is /etc/laptop-mode/conf.d/lcd-brightness.conf. Brightness values are between 0 (darkest) and 15 (brightest). An example of usable settings:

SHE

The eeepc's 'Super Hybrid Engine' has a significant effect on powersaving. This underclocks the FSB for powersave/overclocks for performance and can be controlled via the file /sys/devices/platform/eeepc/cpufv which is provided by the module eeepc_laptop.
You can manage this with laptop-mode-tools. The relevant config file is /etc/laptop-mode/conf.d/eee-superhe.conf.
